ELECTRlC lNSOLE FOR SHQES.

SPECIFICATION forming part of Letters Patent No. 647,647, dated April 17', 1900.

Application filed August 30,1899. Serial No. 728,935. (No model.)

To (tZZ whom it may concern;

Be it known that I, HENRY 0. CAN DEE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Electric Insoles for Shoes, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to electric or electrogalvanic insoles for boots and shoes; and the objects are to provide means to support the center of the foot in a raised position, to keep the feet dry, and to generate a current of electricity for curative purposes.

To this end my invention consists in the combination with a flexible insole of a galvanic couple secured to the same at or near its center in position to support the center of the foot in a properly-raised position; and my invention consists in certain other combinations of parts hereinafter described, and specifically set forth in the claims.

In the drawings hereto annexed and forming a part of this specification, Figure 1 is a top plan View of my invention; Fig. 2 is a side elevation of the same, and Fig. 3 is a modifi cation.

Referring specifically to the drawings, A is a layer of cotton cloth of a size and shape to fit the shoe or boot. B is a layer of hair secured to the upper side of the cloth by rows of stitching. C is a thin plate of copper having curved ends 0 and a curved row of perforations c near each end for ventilation and for the purpose of securing the plate to the cloth and hair insole, and D is a smaller plate of zinc secured at its center to the center of the copper plate 0 by a single rivet E.

The metallic plates 0 and D form an electric or galvanic couple, which may be varied in size, shape, and material. This electric device is preferably curved so that its center is raised and when properly placed in the shoe or secured to the upper side of the flexible insole comes directly in the hollow of the foot and supports the center of the foot or the arched instep or metatarsal bones of the foot. The battery can be detached from the insole and secured to the foot, if desired, by suitable means, as a rubber band or a strap. (Not necessary to be shown or further described.) The moisture of thefoot acting on the different metals produces a constant current of electricity, which passes through the foot and acts in the blood to eliminate the uric acid from the kidneys and other parts of the system, thus preventing rheumatic pains and many other ailments.

This insole, with the electric couple attached, causes the uric acid or perspiration to pass through the hair B of the insole to the cotton cloth underneath, as the hair is next to the stocking, thus keeping the feet dry and cool. The uric acid contained in the perspiration is not absorbed into the system, but deposited in the cotton underneath the hair. The hair allows circulation of air and is also kept substantially dry.

The electric couple may be easily separated from the hair and cloth insole and the latter washed and dried and again attached to the couple. If desired, a zinc plate may also be secured below the copper plate, as shown in Fig. 3 of the drawings.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. The combination of a flexible insole and an electric couple secured to the center and upper side of said insole, said couple being formed of two plates lying one upon the other the lower plate being larger and extending beyond the edges of the upper plate, substantially as described and shown.

2. The combination of a cloth insole havin g a layer of hair stitched uponits upper side and an electric couple secured upon the up per side of the hair, and near the center of the insole, substantially as described and shown.

3. The combination of a cloth and hair insole, and an electric couple consisting of two plates of different metals secured together at their centers by a rivet, the lower plate being larger than the upper plate, said lower plate having a row of perforations at each end for securing the couple by stitching to the insole, said plates being curved to conform to the curvature of the hollow of the foot and attached to the insole directly below the hollow of the foot, as set forth.

4.. In an electric insole for boots and shoes, a pair of thin curved plates of difierent metals, as copper and zinc, said plates being oblong and the upper plate smaller than the lower plate, and a rivet securing the centers of the plates together, said lower plate having perforations in each end, substantially as described and shown.

5. The combination in an insole for boots and shoes of two or more thin curved plates of different metals secured together by snit- I able means, the lower plate having its edges extending beyond the edges of the upper plate -or plates, as and for the purpose described. 10
